Responsibilities :
Developed a large-scale software product focused on multi-project management. Fully
responsible for designing and developing the front-end of an AI-driven virtual assistant
chatbot and associated "assistant agents" for resource and project management.
Delivered the project from initial concept to successful production release, collaborating
closely with designers, product owners, backend developers, and QA throughout the
development cycle.

Technologies (and some libraries) used in the product development included:

 Web Speech API for speech-to-text conversion
 Ng2-charts + Chart.js for displaying various graphs
 Angular material datepicker / angular-mydatepicker for calendar

 Playwright, NUnit

Performed deep refactoring and decomposition of legacy components (5k+ LOC),
improving maintainability and performance.

As I was responsible for the entire frontend aspect of these modules, during the
development process, I learned how to establish effective communication processes with
the owner, designer, backend developers, and QA. I also handled the selection of
necessary libraries and technologies to implement the client's ideas.

In the summer of 2023, I took the first place during the internal AI Hackathon. The
challenge was to develop the most useful project in two weeks, utilizing AI to the
maximum extent during the coding process. I prepared a project which analyzes
compositions of any multi-component products (cosmetics, nutritional supplements,
etc.). In this instance, AI was employed not only for code generation but also for the
application's functionality and in creating a video presentation through the use of
deepfake technology
